there occurs a huge wastage of water due to overflow in overhead tanks.

Approach to Problem Solution: Our main requirements for the indicator are as follows: o Low Power consumption o Compact, with less Electronic complexity o Simplified result o Economical  So the recommended solutions for the above mentioned

requirements are:
o Usage of LEDs enables low battery consumption and

economical.
o Multiple LEDs give a simplified result by indicating the

level of water in the overhead tank.
o Use of a single IC to perform the computation makes it less

complex.

Literature Survey
IC 4066
The 4066 chip is a Quad Bilateral Switch that can be used with digital or analog signals.

Transistor BC148
It’s a plastic version of a standard NPN Transistor and is used for small signal general purpose amplification.

SPST Switch (Single Pole, Single Throw)
A Simple on-off switch: The two terminals are either connected together or disconnected from each other. An example is a light switch.

Strategies to Reduce Monitor Alarm Fatigue
Monitor alarms are designed to alert caregivers to changes in a patient’s condition and can save lives, but majority of the alarms do not require clinical intervention. However, as the number of alarms encountered by clinicians on a daily basis rises, it has become difficult for caregivers to distinguish between...

Track 3: what the beep?
ABSTRACT
The goal of this research is improving alarm sound design, focusing on the paradox of noticeable versus pleasant sounds. The characteristics of annoying sounds correspond in large extend to the characteristics of noticeable sounds. Therefore it is difficult to design an alarm sound, which is noticeable, but not...

...Why does the alarm clock snooze button give you nine extra minutes, not ten?
November 26, 1999
Dear Cecil:
When my roommate's alarm goes off, he invariably presses the snooze bar. This continues in nine-minute cycles until I have to rouse him myself. All the alarms I have seen have a nine-minute snooze interval. Is this a standard number, and if so, where did it come from?
